What does this dream mean?

I dream a lot about running, but I can never run a long distance without falling and collasping. then I'll get up again. constantly. thats all my dream is. Running and falling. And when I daydream about whatever it is, say a day when I ran around...

somewhere, my mind will MAKE me fall! I dunno what it is.

Here's what I found:

A dream of running suggests that you are involved in a situation (or obligation) from which you would like to escape; talk it over with a competent adviser or friend before the resentment has serious repercussions. To dream of being unable to run indicates a lack of self-confidence. Try asserting yourself now and then; you might be surprised at the results

I have dreams about running and not been able to get anywere, like have chains on my feet. I guess its because you dont think highly of youreself and you feel youre never getting anywere. Or maybe you want to change your life but cant
